Einige Bemerkungen über die Gliederung der Triasformation und über ihre Verbreitung in der Umgebung von Bissendorf [PDF]

open access: yes, 2013
Da bei den bis jetzt über die Umgebung von Osnabrück publizierten geologischen Karten bei ihrem kleinen Massstabe auf eine Wiedergabe der genaueren Details verzichtet werden musste und auch zum Teil wenigstens die durch dieselben gegebene Darstellung der

Pliensbachian–Toarcian ostracod biogeography in NW Europe: Evidence for water mass structure evolution [PDF]

open access: yes, 2007
This paper examines the role played by palaeoceanographic and climatic conditions on the palaeobiogeography of the Pliensbachian–Toarcian ostracods (Early Jurassic) in the European Epicontinental Sea (EES).

Neoteny and the Plesiomorphic Condition of the Plesiosaur Basicranium [PDF]

open access: yes, 2006
The purpose of this paper is to describe the condition of the braincase in stratigraphically early and morphologically primitive plesiosaurs. Information on the braincase of plesiomorphic taxa is important because it establishes the polarity of ...

Exploring the influence of sediment heating, thermal maturity and hydrocarbon formation on Hg behaviour in the geological record [PDF]

open access: yes
The use of sedimentary mercury (Hg) as a proxy for Large Igneous Provinces (LIPs) has become an increasingly important area of research. One key limitation in applying and understanding this proxy is its interaction with thermal maturation.

Early Jurassic anoxia triggered the evolution of the oldest holoplanktonic gastropod Coelodiscus minutus by means of heterochrony [PDF]

open access: yes, 2015
The tiny gastropod Coelodiscus minutus is superabundant in concretions of the Early Jurassic Posidonia Shale of South Germany which were formed under anoxic or extremely dysoxic conditions. Previous suggestions that C.

Seawater temperature and carbon isotope variations in belemnites linked to mass extinction during the Toarcian (Early Jurassic) in Central and Northern Spain. Comparison with other European sections [PDF]

open access: yes, 2008
The Early Toarcian mass extinction marks one of the critical events in the history of the Earth. Many of these events have been linked to important climate changes. Two sections of the Toarcian showing high-resolution ammonite-based biostratigraphy are
